`GRAIN LOADER.

Application filed `July 30, 1920, Serial No. 400,054 Renewedltebruary 27,1925.

ments in Grrain Loaders, of lwhich the following is the specification.

1 The invention relates to improvements in f grain loaders and the general object of the invention 1s to provide an` agricultural 1mplement which can be drawn over the field and will pick up the grain lying loose on the field, elevateitand discharge it into a winding belt to form a load and then afterwards discharges the load from i the `belt Von to a cross conveyor having an ele vated end, such construction preventing the` threshing of the grain andthe conse- 'qnent saving of the seed.

A further object is 4to construct the machine so that it is at all times under the direct control of the attendant, the various working parts beingv arranged softhat they can be thrown into and out of commission as -occasion'demands A in view the invention consists essentially in the arrangementand construction of parts hereinafter more particularly described and later pointed outl in theappended claims, reference being hadA to the accompanying drawings in which :n

' Fig. 1 is a side view of the complete rnachine. l

Fig. 2 is al plan view thereof. e Fig'. 3 is aV longitudinal sectional view centrally through Vthe machine.

Fig. 4 is a vertical cross' sectional view at ana Fig. 1.v f

In the drawings like characters of reference ,indicatecorresponding parts in the several A iigures I wish to state that in so far as the present application is concerned I do not consider the lvarious minor details of Vimportance as the invention relatesmore particularly to the novel-means employed for collecting the grain picked up from the field b v the pick up conveyor and the means employed for receiving and `discharging the grain from the latter means.`

Referring now to the. drawings 1 rectangular frame mounted rearwardly on with bearings which v carry equalV advantage; 1 represents a substantially open centered "of a driving .shaft 1' and forwardly on afpair of independent castor wheels 5 and (S,

the'latter wheelsk being steered over the field by draft tongues Vv(not shown) secured thereto.: f i v 1 `More 'oryless centrally of the lengtlrof the'frame I locate two uprightsi7 and 8, the upperends of whichcarry hangers .9 and 10. which supportrotatably the upper con- .veyor cross shaft 11. More or less centrally beneath themain frame I locate an ,under structure 12 presenting downwardly extending corner.` beams 13, 14, andl Aand cross and end beams 17 and 18, 19 and 20. connecting the corner beams. Brace beams 21 and 22 extend forwardly `angularly between the under structure andthe main Aframe and Vangularly disposed rear braces 23 and 24 extend rearwardlybetween the under structure and the main frame. v

beams 25,` 26 `and 27 and these beams" are utilized to supporta pair of parallel angu- A larlyv disposed carrier plates 28 and 29 which -IV ith the above more important objectsv 11, whilstthe lower ends of the platesare loeatedadjacent the ground at the frontend of the machine where `they areprovided rotatably the lower conveyor cross shaftBO. f

On the upper and lower cross shafts I mount pairs of :chain kwheels 31 and ,32

which carry conveyor chains 33 and 34, the

ychains `being provided with crossslats V35 fitted with projecting pick-up prongs 35. The ascending sides of the chains drag4 over the plate 28 and obviously when thefconveyor is drivenin .a proper directionA the' prongs will pick up the grain lying von the field and elevateV it to the highest point of the conveyorV where `it is discharged"-rearf' f fico wardly over the end.v

Whilst I have entered into the details' ofV the construction of the conveyor' I -dou not kconsider the details of the structure `shown essential as r any type of endless pick-up conveyor which willfgather `the grain from the ground and elevate it can be used to at one end with a `bevel 'gear 37 m'eshed Witha bevel-pinion 38 secured to an auXiliary driving sha-ft 39 mounted oir the corner posts 13 and 14. This auxiliary driving shaft is supplied at one end With a pulley 4() and'attheotherend-lwith -a chain wheel 41, the purposes of which will be later described.

Rearwardlyofvthe main vframe I'mount a winding shaft 42 fitted Within the frame luwvi'th -arfpairifof topposingdiscs'43'1and 44` perinanently1 secured "to ithecshaft rand foriniing With-the shaftva'-Winding'drum.

In7 o'rderto Lretard lthe Winding of the belt off thev shaft #36 I 'have supplied f a' flexible cable 62k f. fastened to the main framel and. given fa turn around the shaft 36 and provided at the lower end with a `Weight 63, theaction of the cable Vand" Weight being to actasaa friction brake on 'the said shaft. Y

When this machine is to be used t-he belt *'45 is finitiallytll-wound onthe shaft 36 and it isup'referable to have the grain lying on 'thefield Without being tied in sheaves. This f obviously can beaccomplishedlby dispensing with the services -of the customary knotter found on the -presenttypesfofgbinding machines. :Insthefpiclingup of .thev grain from the ground fthe clutches 47 and 54w are in and z-the clutch 60 isout lwith the result` .that the pick-.up conveyor vis driven. :in a. proper di- :rection to, `cause Vthe prongs to Alift the.

The pulley 40 is then belted to any suitable 'driving part V"0f the thresher andthe clutch 60 is thrown into commission. This causes the driving of the cross conveyor and also the turning rof the-shaft -finuadirection Which vwill Wind the beltz'off the shaft 42-onto1the-shaft f 36.
